BRICK-KILN CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 2, 1921.

Application filed March 22, 1918. Serial No. 224,042.

To all whom it may concern Be it known that 1, JAMES T. POKORNY, a citizen of the United States, residin at Paris, in the county of Lamar and S tate of Texas, have invented certain new and useful Improvements in a Brick-Kiln Construction, of which the following is a specification.

The invention relates to brick kiln, and more particularly to the class of improvements in kiln construction.

The primary object of the invention is the provision of a kiln construction of this character that bricks as Well as tiles may be manufactured, burned'and driedunder the same roof. I

Another object of the invention is the provision of a kiln construction of this character wherein the burning, firing, and drying rooms are arranged in a novel manner and located within a single building adapted for the manufacture, burning and drying of bricks so thata great saving in fuel is accomplished and moreover a considerable reduction in the time required for the burning of the bricks is obtained and a more'uniform and satisfactory product produced. Itwill be apparentthat the use of the heat developed during the burning of the bricks for also effecting the drying of the same is particularly desirable ina brick manufacturing plant and moreover my invention contemplates such an, arrangement of this character as is usually efficient for the ends intended.

Further objects ofthis invention reside in the arrangement of the various fines and fire chamber, in which the bricks are located when being burned to economize on fuel, the particular means being employed for causing the fire to perform the two-fold .function of burning the bricks and drying the same is very effective for these purposes.

With these and other objects in view, the invention consists in the features of construction, combination, and arrangement of partsas will be hereinafter fully described,

illustrated in the accompanying drawings .andpointed out in the claims'hereunto appended.

,In the accompanying drawings:

Figure '1 is a vertical longitudinal sectional view through abrick kiln construction in accordance with the invention.

Fig. 2 is ahorizontal sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical transverse sectional view on the line 3-3 of Fig. 1;

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, it Wlll be seen that the brick kiln construction comprlses a main building 5, which may be of any desirable construction, having at suitable intervals in the sid walls thereof doorways 6 to permit access thereto while in the upper portions of these walls are suitable wlndows 7, for giving light tothe interior of the building and also for permitting ventilation when the occasion requires. Located centrally longitudinally within the building 5 is a continuous substantially ovalshaped kiln of any conventional form, having in the outer side thereof suitable doorways 9, so that ingress and egress can be had to the kiln, and within the latter may be stacked the bricks to be fired in the ordinary well-known manner.

Located at suitable distance above the crown of the kiln 8 and extending transversely within the building 5, are superposed floors 10 and 11 respectively for dividing the upper portion of the building into a drying room 12, and a firing room 13, the latter being above the drying room 12, which has located therein a plurality of tracks lat, over any of which is adapted to travel a truck 15, it being understood of course, that any number of trucks are employed and are adapted to carry bricks for the drying thereof, which takes place within the drying room, while the firing room 13 may be utilized for the manufacture of the bricks or tiles. The building 5 is provided with any suitable type of roof 16, while eXteriorly of said building is located a vertically disposed smoke stack or chimney 17, which may be of any size and height corresponding to the particular size of the brick kiln plant con ran ed in series of the soaced 3i 3% trans-V versely of the kiln 8 and on the removal of the cap from any one of the said pipes 19,

fuel such as coal or other fuel product can be delivered into said pipe through its upper open end from the firing room 1.3.and con- 7 veyed into the kiln 8 for the chargingthere I so that each truck 15 is loaded with the green of with fresh fuel, it being understood of course, that any quantity of green fuel can be stored within the firing room 13 in the upper portion of the building 50f the plant. Located between the foundation for the buildingb and the bottom ofthe' kiln 8, is a: chamber, which maybe constructed in any desirable manner, and is of the required width and length and extending through this chamber at intervals beneath thebottom 22 of said kiln 8 are the horizontal elbow portions 23 of draft flues 24, the upstanding vertical portions 25 of which are located centrally relative to the kiln and extend upwardly, for communication with the main flue 18, while the horizontal elbow portions 23 of said fiues open laterallyas at 26 into the kiln 8 at the outer side thereof. Each vertical portion 25 of the draft flue 24., at its end communicating with the main flue 18, is fitted with a removable damper 27, the same being provided with a lift rod 28, which extends upwardly vertically through the floors 10 and 11, within the firing room 13, where said rod 1s accessible and can be.

manually manipulated for the opening and closing of the damper 27 as will be clearly apparent.

On the opening of the draft fiues 24, directdraft can be had with the stack or chimney 17 through the main fine 18 and the dampers 27 or said draft fiues may be-separately operated as desired for the purpose of regulating the' draft inthe kiln '8 in order to obtain certain particularly efiicient results in operating the kiln as will hereinafter appear. It is desirable to have the dampers 27 usu-.

ally of considerable weight so as to' secure the proper closmg oif'of the fiues 24: when it is-required to regulate the draft in the kiln 8.

In'the'drying room 12, itis understood bricksto be dried, the bricks being elevated n any suitable manner lnto the drying room and loaded upon thetrucks either by hand or otherwise.

In the use of the kiln construction, the bricks are stacked upwardly within the kiln, and are placed in such away as to leave suitable spaces between the stacks of bricks so as to permit the proper circulation of air through the said stacked bricks when the ln'i'cks are belng fired. The stacked brlcks are divided into sections by the use of paper 1 partitions'(notshown) as usual. These paper partitions make each divided section airtight and facilitates the firing of the'br cks in sections. a Y

When starting the fire in-the kiln 8, the damper 27 nearest the stack or chimney 17, is open anda light fire started. 'As soon as the fire gets going,the damper referred to is closed and the next adjacent damper away from the stack or chimney. 17 is-opened, and this operation is continuedthroughout the series of dampersand the heat from the kiln 8 and the main fiue 18 will'rise and pass through rows of openings 29jformed in the floor 10 into the drying room 12 so that the bricks 'stackedthe'rein will become heated and properly dried. Fuel'is deliv'ered to the kiln 8 through the pipes 19' from the fir ng room 18, above the drying'room12, while the control of the firewithinsaid kiln 8'-is efi 'ected by'manipulating the dampers 27 so that the drying room will. become properly heated progressively fromone end of the building 5 tothe other end thereof.

By the time the last sections of the stacked v bricks within the drying room '12 have become heated, the first sections of stacked bricks therein have cooled off so that-the bricksmay'be taken out, of the same,,and a new supply stacked-in substitute therefor, but always the same number of bricks are kept ahead of the fire as are being taken out after being burnt behind the fire. The stacking of the bricks within the drying room 12, and the dividing thereof into sections is; accomplished in "any ordinary well-known manner. I a r From the foregoing, it is thought that the construction and manner of use of the kiln construction will be clearly understood and therefore a more extended explanation has been omitted. j l

What is claimed is: 1. Ina brick manufacturing plant, a fire chamber, drying and firing chambers arranged in superposed relation above the fire chamber, the fioor of the dryingchamber having openingsthereinto admit the heated air circulating about the exterior of the fire chamber, and fuel conducting pipes connect 7 3. In a brick manufacturing plant, a fire chamber, superposed brick drying and firing rooms arranged above the fire chamber, fuel conducting pipes connecting the firing room with the fire chamber, and removable caps engaged with the upper terminals of the fuel conducting pipes.

44:. In a brick manufacturing plant, a firing chamber, drying and firing rooms arranged 10 in superposed relation above the fire chamher, the floor of the drying room being provided with openings admitting the heated air circulating about the exterior of the fire chamber, fuel conducting pipes connecting the firing room with the fire chamber, and 15 removable caps engaged with the upper terminals of the fuel conducting pipes.

In testimony whereof, I aflix my signature hereto.
